Window Company in Placentia, CA
Westlight Windows & Doors is a window and door company serving Placentia, CA, where most of the housing stock dates to the 1960s and 1970s and still carries original aluminum single-pane windows or early dual-pane units that are now fogging. Inland heat and Santa Ana winds punish those old frames harder here than they do in coastal Orange County cities just 12 miles west, and that changes how we approach nearly every job in Placentia. If you’re looking for a window company that gives you a written price before any work starts, call us at (903) 354-7134.
Why Placentia Homes Are Different
Placentia was built on former orange-grove tracts, and the ranches and split-levels that went up in the 1960s and 1970s were framed around narrow rough openings sized for aluminum sliders. That means measurement matters more here than almost anywhere else we work: order a modern vinyl unit without checking the actual framing dimensions first, and you’ll find yourself paying for a custom resizing or a patch-and-reframe you didn’t plan on. We measure every opening before quoting, and the written price reflects those exact dimensions.
The other thing Placentia deals with that coastal cities don’t is the full brunt of Santa Ana season. Hot, dry gusts strip weatherstripping, warp wood door frames, and stress the spacer seals in dual-pane glass until they fail. Homes near the Old Placentia historic district add another layer: those 1920s-1940s Craftsman and bungalow structures often need wood-frame window matching, and some trigger historic compatibility reviews before work can start. We know which streets that applies to and plan for it from the first visit.
Our Main Placentia Services
Most Placentia homeowners call us for one of three things: replacing old windows, installing new windows in a fresh opening, or putting in a new exterior door. Each service has its own Placentia page with full detail.
Window Replacement in Placentia
Replacing windows in Placentia almost always means pulling out aluminum frames that have been in the wall since the Nixon administration. The original single-pane units and the early dual-pane swaps from the 1990s are both failing now, and the inland heat makes that failure expensive every summer. We measure the narrow rough openings carefully, recommend a frame option that fits without unnecessary reframing, and match the product to the elevation: west- and south-facing windows here take a beating in the afternoon. Learn more on our Window Replacement in Placentia page.

Window Installation in Placentia
New window installation in Placentia covers everything from a single bedroom window to a full wall of glass in an addition or remodel. The challenge here is the same as with replacements: those 1960s tract-home openings were built around specific aluminum sizes, so any new opening we create has to be framed, flashed, and sealed to handle Santa Ana wind-driven rain. We coordinate measurements with the framing stage so the units arrive in the right size the first time. Details are on our Window Installation in Placentia page.

Door Installation in Placentia
Door installation in Placentia has a wrinkle most cities don’t: the clay soils under the old citrus tracts shrink and swell with the seasons, which racks door frames and throws slabs and thresholds out of alignment. We regularly rehang and adjust doors in homes along the Atwood corridor and near downtown, and we check the existing frame before any new door goes in. If the frame has moved, we correct it so the new door closes true. Full detail is on our Door Installation in Placentia page.

- Craig Dillard"Our sliding patio door had come off its track years ago and we just lived with it. New one is smooth as butter. They hauled off the old one and vacuumed up before they left."
